1. Introduction
APRO
Industrial 40/44-pin micro IDE Flash (MIF) Disk Hermit Series products are designed to follow ATA/ATAPI-6
standard. The main used Flash memories are Samsung SLC NAND Type Flash memory chips. The available Card
capacities are 128MB, 256MB, 512MB, 1GB, 2GB, 4GB and 8GB. The operating temperature grade is optional for
standard grade 0°C ~ 70°C and industrial grade -40°C ~ +85°C. The APRO Industrial 40/44-pin micro IDE Flash (MIF)
Disk Hermit Series are designed electrically compliant with the conventional IDE hard disk and support True IDE Mode.
The data transfer modes supports PIO mode 0~6, Multi Word DMA 0~4, or UDMA 0~5; Default setting are PIO mode-4 or
UDMA-4. Hermit Series MIF features an extremely light weight, reliable, low-profile form factor.
The APRO
Industrial 40/44-pin MIF Hermit Series provides a high level interface to the host computer. This interface
allows a host computer to issue commands to the Flash Disk to read or write blocks of memory. The host addresses the
card in 512 byte sectors. Each sector is protected by a powerful 4 bits Error Correcting Code (ECC). APRO
Industrial
40/44-pin micro IDE Flash (MIF) Disk Hermit Series, it uses intelligent controller which manages interface protocols, data
storage and retrieval as well as ECC, defect handling and diagnostics, power management and clock control.
